The kit includes 50 Grade 307A lag bolts and 50 USS flat washers, and the biggest reason to buy is the Hot-Dip Galvanized finish that provides real rust resistance for projects exposed to weather or ACQ treated lumber. Our review finds it best for builders, deck installers, and DIYers who need a bulk supply of reliable lag screws and washers without paying for specialty coatings or custom lengths.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity and value:\u003c\/strong\u003e The 50-pack of screws and 50 washers supplies enough hardware for medium-sized projects without repeated trips to the store, which saves time and cost.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion protection:\u003c\/strong\u003e Hot-Dip Galvanized coating offers superior rust resistance compared to plain steel, making these bolts suitable for exterior use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards compliance:\u003c\/strong\u003e Meeting ASTM A307, ASME B18.2.1 and related specs ensures consistent dimensions and material characteristics for industrial or commercial projects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWashers included:\u003c\/strong\u003e Each lag bolt comes with a USS flat washer (1 in OD) to distribute load and reduce wood crushing around the head during installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eACQ compatibility:\u003c\/strong\u003e The hot-dip finish is appropriate for use with ACQ treated lumber, reducing the risk of accelerated corrosion in preservative-treated materials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation guidance:\u003c\/strong\u003e The kit notes that a pilot hole is recommended, which helps prevent splitting in hardwoods and ensures proper torque application.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis kit is aimed at contractors, deck builders, and serious DIYers who need a bulk supply of standard 3\/8 in by 6 in lag screws for framing, ledger attachments, or heavy timber connections.
